Aus
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine ABS-Encoderanordnung zu schaffen, die sich durch einen kompakten Aufbau auszeichnet und in deren Umfeld eine wirkungsvolle und langlebige Abdichtung eines benachbarten Lagers sichergestellt ist.The invention has for its object to provide an ABS encoder assembly, which is characterized by a compact design and in the environment an effective and durable sealing of an adjacent bearing is ensured.
Erfindungsgemäße LösungInventive solution
Diese Aufgabe wird erfindungsgemäß gelöst durch eine ABS-Encoderanordnung, mit:
einem Ringscheibenkern der eine Multipolstruktur trägt, und
einem Dichtringelement, das einen Winkelring und einen daran angebundene Elastomerkörper umfasst, der als solcher eine Dichtlippenstruktur bildet,
wobei der Winkelring einen Zylindermantelabschnitt und einen radial einwärts vordringenden Ringscheibenabschnitt umfasst, welcher die vorgenannte Dichtlippenstruktur trägt, und
wobei der Ringscheibenkern derart ausgebildet ist, dass dieser radial einwärts über die Innenumfangsfläche des Zylindermantelabschnitts des Winkelrings unter Bildung eines ringartigen Überstands übersteht, und
an die Innenumfangsfläche des Zylindermantelabschnitts ein aus einem Elastomermaterial gebildeter Füllkörperring angebunden ist, dessen in radialer Richtung gemessene Dicke größer ist als das in radialer Richtung gemessene Überstandsmaß des Überstands des Ringscheibenkernes.This object is achieved according to the invention by an ABS encoder arrangement, comprising:
an annular disc core carrying a Multipolstruktur, and
a sealing ring element comprising an angular ring and an elastomeric body connected thereto, which as such forms a sealing lip structure,
wherein the angle ring comprises a cylinder barrel portion and a radially inwardly penetrating washer portion which supports the aforesaid seal lip structure, and
wherein the annular disc core is formed so that it projects radially inwardly beyond the inner peripheral surface of the cylinder jacket portion of the angle ring to form a ring-like projection, and
a filler ring formed of an elastomeric material is attached to the inner circumferential surface of the cylinder jacket section, the thickness of which is measured in the radial direction being greater than the supernatant of the annular disk core measured in the radial direction.
Dadurch wird es auf vorteilhafte Weise möglich, am Ringscheibenkern einen relativ kleinen Innendurchmesser zu realisieren und das Dichtringelement und den Ringscheibenkern derart zusammenzufügen, dass etwaige in den Bereich der Dichtlippenstruktur vordringende fließ- oder rieselfähige Verunreinigungen, sowie Spritz- und Kondenswasser durch Gravitation- oder Fliehkrafteinwirkung im wesentlichen vollständig wieder aus dieser Dichtlippenstruktur abwandern können. This advantageously makes it possible to realize a relatively small inner diameter on the washer core and to join together the sealing ring element and the annular disk core in such a way that any free-flowing or free-flowing impurities penetrating into the region of the sealing lip structure, as well as spray and condensation water by gravitational or centrifugal force in the essentially completely migrate again from this sealing lip structure.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung wird der Füllkörperring aus dem gleichen Material wie die Dichtlippenstruktur gebildet. Der Füllkörperring kann dabei insbesondere integral mit der Dichtlippenstruktur gefertigt werden. Zwischen dem Füllkörperring und der Dichtlippenstruktur kann dabei auf dem Ringscheibenabschnitt eine dünne Deckschicht ausgebildet sein, die als solche die Dichtlippenstruktur und den Füllkörperring verbindet. According to a particularly preferred embodiment of the invention, the packing ring is formed from the same material as the sealing lip structure. The filler ring can be made in particular integral with the sealing lip structure. Between the filler ring and the sealing lip structure can be formed on the annular disc portion, a thin cover layer, which as such connects the sealing lip structure and the Füllkörperring.
Gemäß einem besonderen Aspekt der vorliegenden Erfindung ist die Multipolstruktur aus einem Elastomermaterial gefertigt und dabei auf den Ringscheibenkern derart aufvulkanisiert, dass das Elastomermaterial mit einem hierdurch gebildeten inneren Randbereich eine Innenumfangsfläche des Ringscheibenkernes überkragt. Der Ringscheibenkern kann dabei so gestaltet werden, dass jener die Innenumfangsfläche des Ringscheibenkernes innenseitig überkragende Bereich der Multipolstruktur von einer Innenumfangswandung begrenzt ist, deren Innendurchmesser im wesentlichen dem Innendurchmesser der Innenwandung des Füllkörperringes entspricht. Hierdurch wird in besonders vorteilhafter Weise erreicht, dass etwaige sich an der Innenumfangsfläche des Füllkörperringes sammelnde fließfähige Verunreinigungen „glatt“ über die Innenkante der Multipolstruktur abfließen können. Hierdurch wird in vorteilhafter Weise eine Wassersackbildung vermieden indem der entsprechende Raum durch den Füllkörperring belegt ist. Zusätzlich wird durch das Aufsitzen des Encodermateriales auf der Stirnseite des Füllkörperringes eine nochmals verbesserte Abdichtung des statischen Dichtsitzes am Aussenring des Dichtringelementes erreicht.According to a particular aspect of the present invention, the multipole structure is made of an elastomeric material and vulcanized onto the annular disk core in such a way that the elastomeric material projects over an inner circumferential surface of the annular disk core with an inner edge region formed thereby. The annular disk core can be designed so that that of the inner peripheral surface of the annular disk core inside projecting portion of the Multipolstruktur is bounded by an inner circumferential wall whose inner diameter substantially corresponds to the inner diameter of the inner wall of the Füllkörperringes. As a result, it is achieved in a particularly advantageous manner that any flowable contaminants collecting on the inner peripheral surface of the packing ring can flow "smoothly" over the inner edge of the multipole structure. As a result, a water bag formation is avoided in an advantageous manner by the corresponding space is occupied by the Füllkörperring. In addition, a further improved sealing of the static sealing seat on the outer ring of the sealing ring element is achieved by the seating of the encoder material on the end face of the Füllkörperringes.
In vorteilhafter Weise ist es möglich, das Dichtringelement und den Ringscheibenkern geometrisch so aufeinander abzustimmen, dass jener die Innenumfangsfläche des Ringscheibenkernes innenseitig überkragende elastomere Bereich der Multipolstruktur abdichtend auf einer Stirnseite des elastomeren Füllkörperringes aufsitzt. Im Bereich der Kontaktflächen können Mikrogeometrien, z.B. zueinander komplementär konturierte Dichtrillen ausgebildet sein, die als solche die Dichtwirkung dieser Kontaktzone weiter unterstützen, ggf. sogar ineinander eingreifen oder einschnappen.In an advantageous manner, it is possible to geometrically match the sealing ring element and the annular disk core in such a way that the elastomeric region of the multipole structure, which projects over the inner circumferential surface of the annular disk core, is sealingly seated on one end side of the elastomeric filler body ring. In the area of the contact surfaces, micro-geometries, for example, complementary contoured sealing grooves can be formed be, as such, further support the sealing effect of this contact zone, possibly even interlock or snap into one another.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung wird im Zusammenspiel mit dem Dichtringelement eine Dichtungseinrichtung in Form einer sog. Kassettendichtung geschaffen die einen Laufring umfasst. Dieser Laufring ist vorzugsweise einstückig mit einem Schutzring ausgebildet, wobei der Außenumfang des Schutzringes kleiner ist, als der Innendurchmesser des Füllkörperringes. Der Schutzring kann sich damit innerhalb des vom Füllkörperring umgriffenen Bereiches erstrecken und die Dichtlippenstruktur frontal abdecken. Zudem bleibt vorzugsweise die Stirnseite axial unter dem Niveau der Multipolstruktur zurück, d.h. sie befindet sich näher am Lager. According to a particularly preferred embodiment of the invention, in conjunction with the sealing ring element, a sealing device in the form of a so-called. Cassette seal is provided which comprises a raceway. This race is preferably formed integrally with a guard ring, wherein the outer circumference of the guard ring is smaller than the inner diameter of the packing ring. The guard ring may thus extend within the area encompassed by the packing ring and cover the sealing lip structure from the front. In addition, preferably the face remains axially below the level of the multipole structure, i. she is closer to the camp.
Die Dichtlippenstruktur selbst kann so gestaltet sein, dass diese mehrere Dichtlippen bildet. So kann die Dichtlippenstruktur derart ausgebildet sein, dass diese eine am Schutzring anliegende Schutzlippe (beispielsweise eine Staubschutzlippe) und eine am Laufring anliegende Dichtlippe (beispielsweise eine Schmierstoffdichtlippe) umfasst. Zudem kann an der Dichtlippenstruktur auch eine auf eine Stirnfläche des Laufringes zulaufende und auf das Durchmesserniveau der Innenumfangswandung des Laufringes abtauchende Hilfslippe ausgebildet sein, die als solche die am Laufring anliegende Dichtlippe nochmals vom Lagerbereich abschottet. The sealing lip structure itself can be designed so that it forms a plurality of sealing lips. Thus, the sealing lip structure may be formed such that it comprises a protective lip on the protective ring (for example, a dust protection lip) and a voltage applied to the raceway sealing lip (for example, a lubricant sealing lip). In addition, on the sealing lip structure also an on an end face of the raceway tapered and dipping to the diameter level of the inner circumferential wall of the raceway auxiliary lip may be formed, which as such, the sealing lip abutting the race again from the storage area.
Eine besonders robuste und präzise zentrierte Verankerung des Ringscheibenkerns an einer diesen tragenden, insbesondere umlaufenden Struktur (z.B. einer Radnabe) wird erreicht, indem der Ringscheibenkern mit einem den Codierringabschnitt umsäumenden, zylindrischen Mantelring versehen wird. Dieser zylindrische Mantelring ist über einen Ringkantenbereich mit dem die Multipolstruktur tragenden Ringscheibenabschnitt verbunden und stabilisiert diesen. Nach dem Aufpressen des zylindrischen Mantelrings auf den zugeordneten Abschnitt liegt der Ringscheibenkern in verbautem Zustand vorzugsweise plan auf einer Stirnfläche des tragenden Abschnitts, typischerweise einem Nabenflansch, auf.A particularly robust and precisely centered anchoring of the annular disc core to a supporting, in particular revolving structure (for example a wheel hub) is achieved by providing the annular disc core with a cylindrical outer ring encircling the coding ring section. This cylindrical jacket ring is connected via an annular edge region with the annular disk section carrying the multipole structure and stabilizes it. After pressing the cylindrical casing ring on the associated portion of the washer core is in the installed state preferably flat on an end face of the supporting portion, typically a hub flange on.
